Buckling of Asymmetrically Delaminated Three-Dimensional Twisted Composite Beam: Exact Solution
Publication: Journal of Engineering Mechanics
Volume 139, Issue 8
Abstract
The analytical solution of a buckling force of a pretwisted delaminated composite column with a proper consideration of the extensional and bending stiffness coupling and transverse shear effect is presented. The system of homogenous linearized differential equations with nonconstant coefficients obtained for this problem is solved with the help of the mathematical theory of analytic differential systems. The parametric studies are presented considering the effect of slenderness, the length of delamination, the asymmetrical position of delamination, and the transverse shear on the critical buckling force.
